Application filed November 7, 1899 Renewed October 29, 1904. Serial No. 230,605.

To all whom it may concern:

Be it known that I, JOHN B. BARTHOLO- MEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Straw-Stackers, of which the following is a specification, reference being had therein to the accompanying drawm s.

in order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect without limiting my improvements in their useful applications to the particular constructions which for the sake of illustration I have delineated.

In said drawings, Figure 1 is a side elevation of a portion of a threshing-machine having attached thereto an automatic strawstacker embodying my invention, the same being shown partly in section, the outer portion of the straw elevator or carrier being in Fig. 2 is a side view of the same, on a larger scale, with said carrier folded in position for transportation. Fig. 3 is a transverse vertical sectional view on line III III, Fig. 1. Fig. 4 is a plan view of a portion of the mechanism for oscillating the stacker and driving the elevators. Fig. 5 is a side view of the sprocket-gearing directly connected with the upper ends of the elevator-belts. Fig. 6 is a plan view of the rearward-extending frame detached projecting back from the sep arator-frame for supporting the lower inner end of the stacker-frame. Fig. 7 is a view, partly in side elevation and partly in vertical section, showing a slight modification of the gearing or power devices by which the carrier-belts are actuated and the stacker is oscillated. Fig. 8 is a plan view, on a larger scale, of some of the parts shown in Fig. 7. Fig. 9 is a sectional view, on a larger scale, showing a portion of the reversing mechanism illustrated in Fig. 3.

Referring to the drawings, Aindicates a portion of the frame of the threshing-machine, attached to which and extending rearwardly and preferably upwardly is a frame a of suitable construction, having a top casing a and side casing-walls a inclosing a space into and through which the threshed straw is delivered by any usual or suitable means. The outward movement of the straw is limited by a hood or receptacle B, which is attached to the rearward extension of the machine above described. While this receptacle may be of any suitable material and construction, I prefer to make it of sheet metal having an upper semicylindrical part b and a lower contracted portion I), open at the bottom. Through this bottom the straw falls into a hopper or receiver O, which is carried by and moves with the lower portion of the stacker in its oscillations.

The stacker comprises three principal portions-a substantially horizontal carrier D, an inclined elevator E, and an upper carrier F-all adapted to oscillate upon a vertical axis a: as for the distribution of the straw in the usual manner and the upper carrier be ing adapted to turn upon a horizontal axis y to adjust the height of its outer end or to fold it for transportation, as shown in Fig. 2. The said portions of the stacker are by preference composed of three belts or endless carriers d e The belt d is so supported and driven as to form the said horizontal carrier D and the lower or outer part of the inclined carrier E. The belt 6 is arranged at the inner side of and parallel with the upper part of the belt (1 and cooperates with it in elevating the straw. The belt f extends outward from the upper end of the latter belt and carries the straw to the point of delivery on the stack.

The lower support for the stacker is furnished by a frame (F, attached to the lower part of the frame A and carrying at its outer end a bearing a. The lower part of the stacker-frame G is supported by cross-beams g, resting upon a bracket g, which latter is formed with a journal or pivot 9 which fits in the bearing a and is adapted to turn therein to allow the oscillation of the stacker.

d 01 are transverse shafts mounted in suitable bearings on the frame G and provided with pulleys d d, which support, respectively, the inner end and the outer lower corner of the outer leg of the belt (1.

G is the frame of the elevating port-ion of the stacker, attached at its lower end to the frame G and having its upper end connected with the upper pivot of the stacker by a frame G 9 is a shaft or journal constituting such upper pivot and carried by a bracket of. The latter rests upon cross-beams a, carried in turn by a frame a. The latter is constructed as a part of or is carried by the frame a, and the whole construction forming the rearward extension of the threshing-machine frame is strongly braced by inclined struts a extending from one of the cross-girths of the frame A to the upper outer end of the frame a and by rods a", which connect the frame a with one of the upper cross-beams of the frame A. The pivot or shaft g fits in a sleeve g, which is attached to the frame G In the construction illustrated said sleeve is shown as formed with a gear-wheel G attached to cross-beams g which latter form the inner cross connections for the side bars of the frame G I In order to have the parts connected together and operate in the most advantageous manner and without cramping orv binding, it is preferable that the journaling of the hinge devices at g 9 should be upon a vertical axis coincident with that of the parts 9 a at the bottom of the frame. When so arranged, the entire stacker-frame can swing without hindrance horizontally to the right or the left. The framework composed of the parts G G G is rigid throughout and has great strength, so as to properly carry the outer vertically-adjustable delivery carrier-belt f and its long frame F. This outer swinging carrier-frame has the longitudinal sill-bars f, the crossgirths f the side fenders f and the wide fender or hopper-board) at the inner end. In this frame are mounted the rollers f 5 and f those at f 5 being secured to a shaftf through which is received the power and motion that are imparted to the carrier-belt f This adjustable frame is arranged to swing upon the axis at y, which is the axis of the shaft and rollers'at the upper end of the vertical or inshaft is inclined part of the carrier d. Said dicated by H and is mounted in the upper ends of the parts of the frame G. The carrier or belt 6 at its lower end is supported by rollers e on the shaft 0 and at the upper end by the rollers e on the shaft e.

The belts d and e are driven by the shafts II and e*, they bein provided, respectively, with the sprocket-w eels I and J, with which the chain K engages. This chain engages with a driving-sprocket L, which is at the end of the shaft L, which is mounted transversely across the upper and inner frame G At the center of the frame it has a ear-wheel N, which engages with a horizonta bevel N. The latter is secured to a vertical shaft N which is mounted in the cross-framework at O and carries the sprocket-wheel P at its lower end. This sprocketheel is connected by the chain P with the sprocket-wheel P, that is secured to the upper end of the shaft at g .The driving-shaft f of the adjustable carrier-belt f receives power from the shaft H of the vertical or inclined carrier through the gear-wheels R It and the intermediate idler R The wheel R is secured to the end of the shaft H, the wheel R is secured to the end of the shaft f and the wheel R is mounted on the swinging frame-bar or radius-bar 1", which is secured to the adjustable carrier-frame F. When the driving mechanism at the inner end of the frame G is in operation, the power and motion are, through the sprockets P P chain P, bevels N N, shaft L, sprocket L, chain K, and sprockets I and J, conveyed to the two vertical or inclined belts d e, and as .the driving-chain K engages with the sprockets J and I in opposite directions the belts d and e are driven in such way that the adjacent parts move in the same direction, and as the sprockets are of the same diameter and also the belt-rollers the speeds of the two belts are substantially alike, and as the shaft H is, as aforesaid, geared to the shaft f 7 by the wheels R It it will (when driven, as described, by the chain K) impart motion also to the belt f, which motion is in the proper direction because of the idler R The framebar or radius-bar 1, which is attached to the adjustable frame F, is hinged upon the axis of the shaft H, and therefore when the frame F is adjusted-that is to say, when its outer end is lifted or lowered-the gear-wheels R R It are always held in their proper working relation, that power is uniformly transmitted to the belt 7 at all times from the shaft H. Consequently the adjustable-belt frame F can be lifted up so as to be in lines substantially parallel to that of d e, or it can be let down to the horizontal or below it and the carriers be maintainedj in continuous operation.- And inasmuch as the power for all of these parts is taken from the axis about stacker oscillates horizontally, the aforesaid continuous and uniform movement of the belts will be maintained in whatsoever position (to the right or to the left) the frame may be carried around said vertical axis.

In order to adjust the swinging belt-frame F to any desired position-that is, in order to adjust its outer end to either of the operative positions-and in order to hold it in such position after adjustment and in order to even throw it forward with its free end over the thresher-frame, as during transportation, and accomplish all these ends without requiring taking hold of the frame, but, on the contrary, enable the operator to attain them while standing upon the ground, I employ the following devices: S S are bars, preferably of metal, which are secured to the frame F at its inner end, one upon each side thereof. They project to points considerably beyond said inner end, also considerably above the side bars and guard-boards of the frame F. If necessary, they should be braced, as by supplemental bars S, at an angle to thebars S and also secured to the belt-frame. T isa shaft mounted on a horizontal line suitably near the ground on the under or outer side of the frame G, or it can be passed directly which the whole through the bars of said frame, as shown in the drawings. It is provided with windingspools t and also with a crank t and a locking-ratchet t if necessary. From the drums if there extend ropes or cables U up to the ends of the bars or standards S S, and to the latter they are secured. The operator by means of the shaft T can exert a powerful leverage upon the carrier-frame F by winding up the ropes U. When the frame is in any position inclined outward from the vertical, the bars S S, the cable, and the shaft T are in such positions relative to the frame that the latter can be lowered by slowly releasing the cable or raised by winding it up and the relative positions of these parts are such that when the ends a of the cables are about on the line between the axis of the shaft T and the axis of the swinging section the upper end of the latter willbe in such vertical position that its center of gravity will be approxi mately in the vertical plane of its axis. The swinging section can be caused to pass across such planes backward toward the thresher either under the influence of sli ht momentum or by a slight force applied y the hand to the arms or bars S. Instantly after crossing and on its beginning to swing inward over the thresher it is resisted by the cable, and the operator can control its descent by means of the winding-drum. When it is desired to again take the belt-frame away from the thresher and carry it out to its operating position, the above-described steps will be reversedthat is to say, draft is exerted upon the cables by means of the windingdrum until the free end of the belt-frame is brought up to the vertical, and after its center of gravity has passed the vertical plane of the shaft II it is allowed to descend upon the rear side slowly to any desired position.

Heretofore in threshing and straw-stacking machines of this class it has been customary to employ two sets of driving mechanisms, one for actuating the elevators or carrierbelts and the other for effecting the oscillating of the entire stacker mechanism horizontally about a vertical axis. In the present construction I have simplified the machine in this respect and have provided a single driving mechanism from which the power and motion are taken for both elevating and delivering the straw and for swinging the stacker. The devices which effect the lateral movement of the stacker and the reversing mechanism will be described below. At present it is noticed that power from some suitable part of the thresher is taken by belt to the shaft V, mounted above the rear part a of the thresher-frame, and this shaft is connected to a rear cross-shaft W by the chain 11, there being sprockets on the shafts, respectively, at o The shaft W is in the vertical plane of the axis of horizontal oscillation of the stacker.

I believe myself to be the first to have pro vided an attached stackerthat is to say,- a stacker secured directly to the rear end of the thresher-framewhich is held and supported by hinging devices extended over a prolonged vertical line-to wit, a line extending from above the uppermost parts of the thresher-frame to points at the bottom thereof'-and has its belt or belts driven from the upper end. As a result I am enabled to reduce the number and the sizes of the parts which form the hinge connection and also greatly reduce the weight of this part of the mechanism. It has generally been customary to employ mutual engaging rings of relatively large diameter or tracks and series of rollers for properly centering and bracing the oscillating frame and stationary frame. All of these I have dispensed with and have reduced the hinging devices to two short strong pivots or journals, as at g 9 but as these are widely remote from each other and as the intervening framework G G G has its parts rigidly connected throughout the result is provision of a wide base (on vertical lines) for the stacker-frame. All of the heavy parts of the frames G G and the belts and other parts connected therewith ane firmly supported on the short strong rearwardly-projecting frame a and at a point quite near the main frame of the thresher, and therefore the upper frame at G being relieved of the work of vertically supporting all this lower part of the stacker, can be comparatively light and yet be-a strong brace or stay frame for the upper portion.

By placing the belt-driving mechanism in a position such as that herein presented I am enabled to apply the power to the belts with great advantage. The belts are practically divided into two elements, one of which is driven at the head or upper endto Wit, the belt dthis resulting in great econ omv of the power for actuating the carriers, and the power is applied to the adjustable element of the stacker from points close to its inner end and on lines which coincide with the lines of movement of the belt f or nearly coincide with them during the greater part of its op-v eration.

It has been generally common heretofore to attain the vertical adjustment of the outer end of the stacker by swinging it around the axis of the lowermost roller, the one corresponding to that at d but in this respect the present machine radically differs from the earlier ones in having the stacker-frame rigid throughout (as the parts G GM) to points relatively high. This obviates the necessity of lifting and lowering a large part of. the heavy framework. Then to compensate for the loss arising from the lack of vertical adjustment of the inner part of the stacker-frame I place the upward and downward extending part E at a sharp angle and maintain it there, this frame being rigid, as above described, and to insure that although thus nearly vertical it shall rapidly and properly carry up the straw I combine with it the under acting belt 6, which prevents the straw from falling away from the belt 61 and assists in its upward propulsion.

It will be readily seen that in many respects there can be departure from the details of construction which are shown wit out departing from the essential features of the invention. The upwardly-inclined part of the belt (1, for instance, may be separate from the lower part below the straw-hopper without essentially altering many of the other parts of the mechanism, though I prefer the present construction and arrangement of this belt, as it simplifies the driving devices and enables me to actuate the belt both of the upper or outer swinging framesection and of the lower or inner section with economy of power. As the lower or inner section of the stacker-frame is throughout all of its parts fixed in relation to the vertical axis around which it swings horizontally, the relative positions of the power parts which convey the power to the upper end of the inner belts and the inner end of the upper belt remain fixed, and therefore uniformly efficient, whatsoever positions the belts may be in relative to the vertical axis.

A special rest or support is by preference provided for the outer carrier-frame F when in its folded position. In Figs. 7 and 8 this rest is shown as consisting of a bar g, carried by legs or brackets 9 fixed on the frame G So far as the features of my invention thus far described are concerned the shaft g may be driven by mechanisms of various forms and the stacker oscillated by any suitable means. I have, however, devised a special mechanism for both of the above purposes having important features of simplicity and efficiency, which will now be described. The shaft W having always the same direction of rotation, that the carrier-belts may be properly driven, has fixed or pinned on it a bevelwheel 1, Fig. 9. 2 is a horizontal bevel-pinion fixed on the lower end of the shaft g and engaged and driven by the wheel 1. Motion in a constant direction is thus imparted to the elevating and carrying belts through the mechanism already described leading from the shaft g and sprocket P With this beltdriving mechanism I combine the oscillating devices for the stacker-frame for automatically turning the latter from side to side on the pivots g g". Arranged in line with the shaft W is a reversible shaft 3, mounted at its outer end in a suitable bearing or bearings 4 on the frame a. and at its inner end preferably fitted in a bearing 5 within the wheel 1. 6 is a bevel-wheel loose on the shaft 3 and held in constant engagement with the pinion 2. 7 is a worm fixed on the shaft 3, which may conveniently hold the wheel 6, as above described. 8 is a double clutch engaged and rotatedwith the shaft 3 by means of a spline 9, on which it may slide either to engage a corresponding clutch member 10 on the wheel 1 or the clutch member 11 on the wheel 6. 12 is a shifting-lever connected with and adapted to slide the clutch 8 and controlled by a spring 13, which tends to force the lever and clutch into either of said engaging positions when the lever has passed the central point of its path. When the clutch 8 is clutched with the wheel 6, the worm 7 will, through the shaft W, wheels 2 and 6, and shaft 8, be driven in the direction of the arrow 14, Fig. 9, oppositely to that of the shaft W. When the lever 12 is shifted to its other position, the shaft 3 will be clutched with the wheel 1 and shaft W and rotated with the worm in the same direction oppositely to the arrow 14, leaving the wheel 6 free to run with the pinion 2 but it will be seen that this reversal does not affect the constant rotation of the pinion 2. The reversing worm 7 engages a worm-wheel 15, fixed on or clutched with a vertical shaft 16. The latter is mounted in a suitable bearing 18, carried by the frame a a a, and has fixed on its upper end a spur-pinion 17, which engages and drives the wheel G sleeve 9 and frame G in a direction dependent upon the direction of rotation of the worm.

The clutch-lever 12 is shifted by pins 19, fixed in the wheel G at suitable points, Figs. 3 and 4, or in some part actuated by said wheel and properly located with reference to said lever. Several sockets 20 may be provided for said pins to allow for an adjustment of the latter, which will vary the horizontal play of the stacker in an obvious manner.

The stability of the frame Gr may be enhanced by a wide bearing-ring 21, fixed on the bars a by brackets 22 and engaged by rollers 23, journaled in brackets 24, fixed on the bars g, Figs. 3, 7, 8.

In Figs. 7 and 8 the principal power-shaft is shown at W, driven from the right side of the machine by a belt-pulley W The worm and worm-wheel are correspondingly changed to the left side of the machine, as shown.

To disconnect the stacker from the oscillating mechanism and allow it to be manipulated from the stack, a handle X may be employed, by which the worm-wheel can be unclutched from the shaft 16.

For convenience of description I herein refer to the belt-frame G as being vertical, meaning thereby that it extends upward in a direction approximating more or less closely to one perpendicular to the horizontal, but not meaning to be understood as limiting its position to an absolutely vertical one, as

IIO

such position can be varied within practical limits without departing from the essential features of the construction. I also refer to the fact that the frame G has all of its parts fixed in relation to its vertical axis, meaning thereby that this frame G is not, as in many earlier constructions, supported upon a horizontal hinge at the lower end, around which it can be swung and adjusted.

I herein claim means whereby the inner roller of the outer elevator-section is enabled to turn over the upper roller of the inner elevator-section; but the specific features of the hinge connection between the said elevator are not claimed herein, but are claimed in my application, Serial No. 18,098, filed May 26, 1900.
